1.Left and right Bleed Air Systems (BAS)
2.Air conditioning system
3.Wing Anti-ice (WAI) system.
171

What is the AMSC responsible for?
The AMSC (Air Management System Controller) is responsible for Bleed Air Management.
Basic functions include:
1. Engine port selection;
2. Regulation of pressure, temperature, and flow delivered to the pneumatic manifolds;
3. Bleed air cooling utilizing engine fan air, Wing Anti-ice, and Isolation between the left bleed air source and the right bleed air source.
174
In the event of a failure of the automatic system how is flight deck and cabin temperature controlled?
Manual backup temperature control is provided by selecting MAN TEMP CONTROL on the ECS panel, which provides direct position control of each zone Trim Air Valve by the Cold/Hot knobs on the Temp Control Panel.
175
What happens when the operator selects the TEMP CONTROL to MAN (manual)?
The temperature control knobs directly control the position of the associated trim air valve.
176

Yes, by placing the cursor over the appropriate °F or °C toggle (located on the bottom right of the display) and selecting it.
177
What type of air comes from the overhead gaspers?
Gasper air is supplied via a cold air duct routed directly from the cold air plenum to the upper cabin pressure bulkhead through a check valve.
178
How is pressurization achieved?
The Cabin Pressure Control System (CPCS) regulates the outflow of air from the cabin at rates required to maintain the cabin altitude according to preset schedules.

The CABIN ALT rotary switch is used to increase or decrease cabin altitude during manual mode.
181
What is the function of the DUMP Switch on the CPCS?
Depressing the DUMP switch provides an open command to the OFV that is rate-limited to 8,000 fpm and altitude limited to 14,900 ft (if above 14,500 ft) or ambient pressure (if below 14,500 ft).
182
What is the function of the DITCH Switch on the CPCS?
DITCH selection is incorporated to close the OFV in case of aircraft ditching.
183
Describe aircraft operation when ADM is activated.
11 things happen when ADM is activated
• Red ADM on PFD’s
• Cabin Altitude High Warning message
• Lateral mode changes to HDG
• Airplane turns 90° LEFT of course
• Autothrottles to idle (automatically engage)
• ALT selector resets to 15,000
• Airspeed to MMO/VMO
• HDG capture after 90 ̊ turn
• 5 secs into ADM – Transponder to 7700
• 15,000 Altitude capture
• Aircraft enters left orbit at 225 KIAS
184
With a rapid loss of cabin pressure what is the first thing the crew should accomplish?
Don personal oxygen mask and ensure mask is set to 100% oxygen.
185
When is wing anti-ice prohibited?
Wing Anti-Ice is not recommended above 10°C TAT or below -40°C TAT to prevent ITT exceedance.
Operation of the WAI system above 26,000 ft with a single bleed air source is prohibited.
186
If the Anti-Ice switches are set to AUTO, when will the Anti-Ice come on?
Anytime ice is detected while climbing 1500 ft AGL to FL350 and descending FL350 to ground.
187
When does the amber Ice Detected CAS message extinguish?
If ice accumulation is < .020” for one minute, the amber Ice Detected CAS message extinguishes.
188
Where is wing anti-ice exhausted overboard?
Hot air flows through the leading edges of each wing, passes through the main wheel well, and then exit out of center vent underneath and between main wheels.
189
What happens when the Wing Anti-Ice is selected to ON?
The WAI operates regardless of altitude, ice detection or whether the aircraft is in-flight or on the ground.
190
What do blue (cyan) wing anti-ice lines indicate on the Bleed / Anti-Ice synoptic page?
Wing anti-ice temperature ≤ 100°F for two (2) minutes of system activation.
191
What is the purpose of the probe heat OVRD position on the PROBES HEAT switch?
It allows the heating of all probes while on the ground as well as in flight.
192
What is the difference between selections of NORMAL and EMERGENCY?
In NORMAL, it allows regulator to provide diluter-demand flow, and in EMERGENCY position, it sets regulator to provide constant positive pressure flow.
193
How can the tension in the mask harness be adjusted to make it more comfortable?
Using a comfort toggle on the front of the mask.
194
What action must passengers perform to get oxygen to flow into the passenger mask retaining bag?
Pull on the lanyard to remove the flow pin.
195
How is the aircraft normally refueled?
Through the single point connection located on the right front side fuselage.
196
Is there an alternate method to fill tanks and are there any limitations?
Yes, the wing tanks and feed tanks can be filled by a single gravity refuel point on each wing.
197
What will stop the jettison process?
Fuel jettison will stop manually by pilot inputs by selecting the “FUEL JETT” switch off, or AUTOMATICALLY at 800 lbs of fuel remaining per side.
198
Can the airplane be fueled using the external Refuel/Defuel panel without turning on main aircraft power?
Yes. The RDP is powered by the Right Hot Bus and only needs to have its power switched on at the panel (the red master switch).
199
What defines a balanced field?
It is where the accelerate-go distance equals the accelerate-stop distance (i.e. shortest takeoff field length).
200
When is a runway considered to be contaminated?
When more than 25% of the runway surface area (whether in isolated areas or not), within the required length and width being used, is covered by surface water more than 0.125 inch (3 mm) deep, or by slush or loose snow equivalent to more than 0.125 inch (3 mm) of water.
201
What is the definition of stopway?
An area beyond the actual runway length capable of supporting the airplane in an aborted takeoff, which can be used as part of the available accelerate-stop distance.
202
What is the definition of clearway?
An obstacle-free area beyond the actual runway length which can be used as part of the accelerate-go distance available on a dry runway. No clearway credit is allowed on a wet runway.
203
What is the definition of V2?
Takeoff Safety Speed. The target speed to be attained at or before reaching 35 ft above the take off surface following an engine failure.
204
What is the definition of VSE?
The recommended airspeed for single-engine climb in the enroute (clean) configuration.
205
What is the benefit of taking off with 10° flaps?
Results in higher climb gradients, and will permit higher takeoff weights when climb limited or obstacle clearance limited.
206
What is the definition of Basic Operating Weight (BOW)?
It is the weight of the aircraft excluding payload, passengers and usable fuel. It includes fixed equipment, unusable fuel, oil, hydraulic fluid, crew and operating items (equipment and supplies) necessary for aircraft operations. When a jump seat is installed, the BOW includes the weight
of a third crewmember.
